l Application filed January 16, 1925.

Holbrook, in theco-unty of Norfolk, Statev of Massachusetts, have invented certain new and useful Improvements in Splicing Tools, of which the following is a specification.

. This invention relates to an improved tool or implement for splicing the ends of transmission bands and belts, or for other rThe principal object ofthe improvement is 'Y to provide a tool or implementm the natu-re ofA a needle or bodkin -for userin in-A serting the ends of the band or belt into the` K tubular stripv to form the splice, and further for sewing strands ofthe material through the splice to finishv off the joint.

Another object of the improvement Vis to provideqa tool or implement of thechar-` acterdescribed having means for automatically gripping the end of the band or belt which is-v to be threaded throughthe interior of the tubular fabric. f

vAnother object of the improvement is to provide a tool or implement of the character described which is light in weight, convenientY to handle and easy to operate.

Another objectof the improvement is tev providefa tool or yimplement of the character described which is simplev in construction, economical to manufacture and strong and durable inuse. Y

Further objects ofthe improvementare set forth in the following specification which describes a preferred embodiment of the invention as illustrated by the accompanying drawings. In the drawings: e

" of using the tool or implement for sewing the strands or threads through the splice in the band or belt. i

My improved tool orv implement takes the form of an elongated needle or bodkin 2,

preferably constructedl from thin sheetmetal. ViA strip of. sheet-metal is-bent or rolled into tubular form, with the edges of ...ITED STATES PATENT OFFICE. f'

the strip meeting in a seam 8 extending longitudinally along one side thereof, and a blunt' point 4 at one end,-see Fig. 2. .At the opposite end of the tool or needle 2 thelseam 3 sidesrspread apart to form a shallow groove or recess 5 extending approximately oneis openedV vand the quarter the,y whole length of the needle.

Preferably, the end of the hollow recessed portion 5 of the tool or needle 2 is lbeveled y or cut oil at an angle as indicated at 6 in Fig. .2. Overlying thek recessed portion o r groove v 5 ofthe tool or needle 2 isa spring-latch 7 having portion of its length held within the confines of the main' tubular. bodyr of the needle.` The latch 7 comprises y"arelatively narrow str in place.V The proJectingportion of the hold the latch firmly y ip of springmetal arv ranged" with its end inserted into the. tubulatch7 is arched upwardly at itscenter and bent down at its end to provide a projection 8,'preferably notched at 9- to form pointsor teeth lO, seeFig. 4. The rteeth l()V are received within'fthe hollow trough-like groove or recessv 5 of the tool or needle 2 to.

adapt them to grip the strands of the fabric banding inserted thereunder. The method of using the improved tool or implement in splicing the 'ends'A of the fabric strip to form the band or belt is as follows:

In splicingthe stripy of tubular fabric tov form 'an endless'band or belt by the method shown and described in my cofpending application, SerialNo. 2943, filed January 16, 1925,1the ends ofthe fabric F are reduced in thickness and preferably tapered toward the tip as shown at f v drawings. One of the tapered'ends f is inserted into from the tip of the other in Fig. 1 of the present' ica' the side of the tubular fabric F tapered endf Vand drawn through the tube v so as yto extend alongl its interior to kform one lap of the splice.

After the first end of the banding has been inserted into the strip as above described the second end is drawn Y into the first end in the same manner to extend along its interior in the opposite direction. A smooth, even splice is thus formed with the ends lapped one Within'the other to adapt the tubular outer fabric to grip the lengths inserted therein. Before inserting the ends of the Ybanding one Within the other the tapered portions are usually waxed or otherwise Vtreated to stiffen the fabric and amalgamate the strands to prevent them from unraveling or Afraying out. In' inserting the ends of the strip of Ybanding into the sides of the tubular fabric it is desirable to use a needle or bodkin to draw' the lengths through the interior of the tube, and my present tool or implement is most convenient and efficient for this purpose. The tapered end f ofthe fabric is attached to the end of the needle 2 by simply lifting the latch 7 and placing the strip thereunder. .l/Vhen `the latch 7 is released it will spring back into place to causeits teeth l0 to grip the fabric F to hold the end of the strip Within the groove 5 at the end ofthe needle. As the tool or needle lis pierce-d through the side of the fabric F at g, pushed through the interior thereof and pierced outwardly again at 7L, it is caused to draw the tapered end f of the fabric into place Within the tube F in the manner more fully eX- plained in my companion application previously referred to. As the needle is drawn through the interior of the tube F the latch 7 acts as a guard to prevent the outer fabric from sticking or clinging to the end yf being drawn into place on the interior of the tube. After the needle 2 has been Withdrawn at the pointv la the latch 7 is released so that the needle can be pulled through and the end f of the fabric F left Within the. spliced portion of the band.

In some cases, after the mill-banding has been spliced in the manner above described. it is desirable to sew one or more strands of the fabric through the splice to prevent the joint from .spreading Where one end enters the other. My present improved tool or implement is most convenient for this purpose, one or more strands s Vbeing pulled out from the fabric and sewed through the splice as illustrated in Fig. 6. Usually the needle is pierced through the fabric first and the end or ends s then caught under the latch ltubular needle having a so as to be seWed through the fabric When the needle is drawn clear through.

lt will be observed that my improvement provides a particularly simple, convenient and efficient tool or implement for the purpose specified, and one Which may also be used for other purposes in various arts. The construction of the needle is especially simple and makes for economy in the .cost of its manufacture, besides rendering the device light in- Weight and therefore more convenient to handle.

Various modifications may be made in the form and structure of my improved tool or in'iplenient Without departing from the spirit or scope of the invention. 'l`l1erefore, without limiting myself as to the exact details herein illustrated and described, I claim: g

' l. A tool or'implement consisting in a tubularneedle pointed at one end and provided at thekopposite end with a recess er:-v tended longitudinally thereof, With a resilient spring-latch overlying the recess to adapt it to grip the material held therein.

2. ln a device of the type specified, a point at one end and a groove at its opposite end, and a resilient spring-latch held in the tubular portion of the needle and Aoverlying the groove at its end to adapt it to grip a strip of material held in said groove.

3. An implement of the type specified constructed from .sheet-metal rolled into tubular form and pointed at site end of the tube having its sides spread apart to form a longitudinal recess, and a spring-latch inserted into the tubular portion of the needle with its free end extending above Ythe open part thereof to adapt it to grip a strip of material held in the recess.v

et. ln a device of the type specified, artubular needle formed from sheet-metal rolled With its edges meeting in a seam extending longitudinally of the needle, the edges of the seam being spread apart at one end of the needle to form a troughelike reeess,'and a spring-latch comprising a` thin strip of metal having one end inserted into the tubular portion of the needle and held by the Walls thereof and its projecting end overlyinglthe recessed portion of the needle'and formed with teeth for the purpose specified.

In testimony whereof I alix my signature.
